Detailed Description

A message within a PbbPacket packet.

There may be any number of messages in one packet packet. This is a pure virtual base class, when creating a message, you should instantiate either PbbMessageIpv4 or PbbMessageIpv6.

void ns3::PbbMessage::Deserialize ( Buffer::Iterator & start )

Deserializes a message from the specified buffer.

Parameters:

start

Users should not need to call this. Blocks will be deserialized by their containing packet.

uint8_t ns3::PbbMessage::GetHopCount ( void ) const

Returns:: the current number of hops this message has traveled.

Calling this while HasHopCount is False is undefined. Make sure you check it first. This will be checked by an assert in debug builds.

uint8_t ns3::PbbMessage::GetHopLimit ( void ) const

Returns:: the maximum number of hops this message should travel.

Calling this while HasHopLimit is False is undefined. Make sure you check it first. This will be checked by an assert in debug builds.

Returns:: the address of the node that created this packet.

Calling this while HasOriginatorAddress is False is undefined. Make sure you check it first. This will be checked by an assert in debug builds.

Tests whether or not this message has an originator address.

Returns:: true if this message has an originator address, false otherwise.

bool ns3::PbbMessage::HasSequenceNumber ( void ) const

Tests whether or not this message has a sequence number.
